wherein it is desired to maintain the printed web intact after it is'fed from the platen.

In my co-pending applicationfiled DecemberZO; 190?), Serial- No.534C970, onwhich this invention is an improvement, several webs are fledtogether around the platen, the bill's forming one web being tornoffione by one toaecompa-ny the purchases, while the copy web is carriedrearwardly to'a spool or reel on which it iscoiled.

@ne oby'eot of this invention is toimprove themanner of coiling thefragile web, and to avoid injury thereto, to which end I lead a guidewhich is automaticausing one end thereoii' to cally adjusted by or rideupon the winding roll,-

press against whereby the incoming Webis straightenedprior to coiling onthe roll; and as the'diameter of the roll increases, the web is direetedor guided to the cirou'mierenee thereozfi, without liability ofkinking-or bending. Advantage is also taken of, the pressure ot theadjustable guide against thev roll-to aid the web in coiling snugly, andalso to constitute a brake to prevent the web from: uncoilingaccidentally.v

Another obj eot is to enable the leading end of the web to be easily andquickly fastened to-the spool or reel, and in such manner that thecoiled webma-y be: easily removed.

This is accomplished. by providing ,th'e' spindle ot the spool with aclamp or catch,

by whi b one endoa? the webi'ssecured, said spool having a removablehead to allow thecoiled: web'tobe slidden: endwise' ofi from-thespindle, the leading end of the web sliding. easily from: beneath heclamp asthe? coiled- Web is sliddeir oil.-

Pa er rolls 1 and 2 are mounted on shafts 3 an 4:, the webs 5 and 6being led from the rollsover the rounded head: 7 of the paper shelf 8-oil an Underwood writing machine, thencepassing around the platen 9(againstwhich' they are held by front and rear presisu-re rolls 10 and11) and upwardly in {front ot the platen printing point. The ilea'dingends oi the websmay be folded as ,shown at 2 k (\Fi 5) beforeintroduction betweenthe platen and the pressure: rolls. In the presentinstance, the web 5, leading yfromthe-paperroll 1,. may comprise salesislips arranged in series, which are torn off successively as theyuareprinted upon, to ac-v Ecompanythe purchases. The web 6 constitutesadiiplieate' record, to be preserved, it 1 being-led backwardly from theplaten 9, and ',wound upon a spool or reel 18, 19, 20, from zwhiehthecoiled web may be removed from ltime to time; The shafts 3, at,supporting {the paper rolls, are mounted in a casing 12, relatively towhich the platen 9 travels back and forth, said casing being. closed bya cover 13- hlnged at 14. The spool or reel 18, 19, 20, on which thewebG is wound, may be 1 journal'ed in the bracket arms 15, securedto thecover."
